文法分析程序修正

可能报错的程序段

位置：Compiling-principle-experiment/Parser/SyntacticParser.cpp

修改

将 for 语句中首项定义 set<T>::iterator it = set_T.begin(); 改为 typename set<T>::iterator it = set_T.begin(); ，即：

template <class T>
void check_set(set<T> set_T, string tip) {
	cout << endl;
	cout << endl << tip << endl;
	for(typename set<T>::iterator it = set_T.begin(); it != set_T.end(); it++) {
		cout << *it << " ";
	}
}

错误原因

模板参数作容器参数时会被编译器错认为是数据类型而导致编译不通过，应添加 typename 声明其为数据类型。
